摘要
根据台湾省及东南亚地区高空天气因资料及探空资料,分析东风喷射气流1)之平均位置和特性,并就青藏高原、副热带西风喷射气2)和东风喷射气流之关系,讨论东风喷射气流之成因以及对北半球天气和气候之影响。东风喷射气流之南北两侧存在着极强烈的温切现象3),这种温切现象不但与东风喷射气流有关,而且对高空民航机之飞航安全有极重大的影响。
he qualities and the causes of the tropical easterly jet stream over Asia and Africa are described,the relationships among the Tibetan High and the easterly jet stream in the upper trope sphere and the climates in the region of the Asia and Africa are also discussed.Temperature shears occur frequently in the vicinity of the tropical easterly jet stream over Asia,therefore the vicinity of the tropical tropopause 16-17km has now become a region of interest to high--level aviation. We must pay more attention to study the information regarding the tropical easterly jet stream at this altitude over nearly half of the tropics for about half of a year.
